The fundamental precept at the back of a diaphragm pacing device (the U.S. Food and Drug Administration identifies the device as a “diaphragmatic/phrenic nerve stimulator”) includes passing an electric contemporary thru electrodes that are attached internally. The diaphragm contracts, increasing the chest hollow space, inflicting air to be sucked into the lungs (concept).

In May 2020, Canadian agency Lungpacer Medical received popularity of emergency use through the USFDA amid the COVID-19 pandemic.
